The invention provides a data acquisition card, equipment and method, and relates to the field of vehicle data acquisition. The data acquisition card is characterized in that the input end of each path of data acquisition module is connected with a wheel speed sensor, the output ends of the four paths of data acquisition modules are connected with the SOC to obtain wheel speed pulse signals acquired by the wheel speed sensors, the SOC is further connected with a timer, and is used for recording the time of the timer as a wheel speed timestamp when the change edge of the wheel speed pulse signal is detected; the input end of the CAN chip is connected with a CAN bus, and the output end of the CAN chip is connected with the SOC to collect CAN signals. Compared with the prior art, the problem that the wheel speed timestamp cannot be collected or is difficult to collect is avoided.

    本申请提供一种数据采集卡、设备和方法,涉及车辆数据采集领域。该数据采集卡包括:每路数据采集模块的输入端连接一个轮速传感器,所述四路数据采集模块的输出端均连接所述SOC,以获取各所述轮速传感器采集的轮速脉冲信号,所述SOC还连接所述计时器,以在检测到所述轮速脉冲信号的变化沿时记录所述计时器的时间作为一路轮速时间戳;所述CAN芯片的输入端连接CAN总线,所述CAN芯片的输出端连接所述SOC,以采集CAN信号。相对于现有技术,避免了无法或者很难采集到轮速时间戳的问题。
